PAPER-STRAlGHT EN ER FOR PRlNTlNG-PRES'SES.

SPECIFICATION forming part of Letters Patent No. 478,079, dated July 5,1892.

Application filed March 5.1892.

To all whom it may concern.-

Be 1t known that I, ALFRED BINKARD, a citizen of the United States ofAmerica, residing -in juxtaposition to the vibrating fly of a press,

having. improved means thereon for straightening the edges of papers asthey are placed thereupon from the press, in the construction andapplication of the mechanism for operatin g the device by means ofmotion imparted by the press, and in certain other features ofconstruction and combination of its various parts, as hereinafter setforth, pointed out in my claims, and illustrated in the accompanyingdrawings, in which Figure 1 is a top or plan View of the com pletedevice, the dotted lines thereon showing the direction in which theguide-bars operate. Fig. 2 is an end elevation of the same. Fig. 3 is anenlarged detail View of a portion of the vibrating fly of a press, itsframe which supports it, and the lever or shaft which operates it toillustrate the manner in which the means for actuating the straighteningdevice is connected therewith. Fig. 4:lS an enlarged detail perspectiveview of one of the guides. Fig. 5 is a perspective view of one of thecorners of the table, showing the means for returning the guide-arms totheir normal position after they have been moved in one direction. Fig.6 is a vertical sectional View through the line a: as of Fig. 1, andFig. 7 is alike view through the line .2 2, same figure.

Referring to the accompanying drawings, the reference-letter Adesignates a rectangular table supported on the legs A B are rodssecured to one side of the table angles to the side thereof in groovesformed $en'al No. 423,807. (No model.)

in the table-top to lower the rods relative to sheets of paper placed ontop of the table.

B is a guide-bar adj ustably connected with the rods B by means of theeyebolts B encircling the rods B and extended upwardly through the bar Band provided with athumbnut B as clearly illustrated in Fig. 7.

C is an auxiliary guide-bar adj ustably attached to the bar 13 andextended at right angles thereto.

D represent guides adj ust'ably fixed to the guide-bars B and O atsuitable distances thereupon to engage the edges of the papers. Theirfront and bottom edges are smooth and flat.

D? are metal blocks secured to the said guides and transversely bored toadmit the said guide-bars.

D is a set-screw in a vertical bore which intersects the aforesaidtransverse bore.

F and F represent guide-bars similar to the bars B and C, respectively,and also provided with the guides D at suitable distances thereupon.

H represent crank-wheels rotatably mounted in the angle-irons H fixed tothe top of the table and at the edge opposite to the one to which therods B are secured. To their inner top surfaces the guide-bar F ispivoted, so that when a rotary reciprocating motion in the segment of acircle is imparted to the said crank-wheels a rotary reciprocatingmotion in a plane diagonally across the table will be imparted tothesaid guide-bar.

To provide means for actuating the hereinbefore-described mechanism fromthevibrating fly of a printing-press, I employ the following mechanism:J are crank-arms formed on or fixed to the two outercrank-wheels andextended outwardly therefrom. J 2 is a rod or rope (preferably thelatter) secured to the outer end of one of the said crank-arms and to anextension J 3 on the outer end of the shaft which actuates the fly ofthe press, as clearly shown in Fig. 3 of the drawings. This arrangement,it will be seen, actu'ates the guide-bars in but one direction. Krepresents a coil-spring attached to the outer end of the othercrank-arm and to the table to return the guide-arms to their normalposition.

I provide means for limiting the forward stroke of the guide-bars asfollows: L represents a frame secured to the side of the table andhaving the top surface provided With a series of vertical bores to admita pin L The said crank-arm, being extended therethrough, will engage thesaid pin on its forward stroke, and thereby limit its movement. I preferto arrange the guide-arms on one side of the table in a higher planethan the other ones, so that they may be adjusted to small papers andoperate without interfering with each other, as shown in Fig. 2.

Having thus described my invention, what Iclaim as new therein, anddesire to secure by Letters Patent, is-

1. In a paper-straightening device, the combination of a plurality ofrods fixed to one side of the top surface of atable and extendedinwardly in grooves formed in the top of the aforesaid. table, aguide-bar adj'ustably connected with the said rods, an auxiliaryguidebar extended at right angles thereto and adjustably connectedtherewith, and a plurality of guides having smooth front surfacesadjustably fixed to the said guide-bars, and means for bringing sheetsof paper in contact with said guides, substantially as and for thepurposes stated.

2. A paper-straightening device com prising a table arranged to receivethe papers from the vibrating fly of a printing-press, a plurality ofcrank-Wheels mounted in the top of the said table, a guide-bar pivotedto the front edges of the said crank-wheels, an auxiliary guide-baradjustably attached {to the fsaid guide-bar, guides connected with thesaid guide-bars at suitable distances therefrom, means for engaging theopposite edges of the papers, and means for actuating the saidcrank-Wheels, substantially as set forth.

3. A paper-straightening device comprising va table arranged to-receivethe papers from the vibrating fly of a printing-press, adjustable guidesattached to one side and end of the table at right angles to each other,a plurality of crank-wheels mounted on the top of the'said table, aguide-bar pivoted to the front edges of the said crank-wheels, anauxiliary guide-bar adjustably attached to the said guide-bar, guidesconnected with the said guide-bars at suitable distances thereupon,crank-arms secured to the outer crank-Wheels and extended outwardlytherefrom, means for connecting one of thesaid crank-arms with the shaftwhich actuates the vibrating fly of a printing-press, a spring attachedto the outer end of the other crank-arm and fixed to the table toactuate the guide-bar on its return stroke, and means for limiting theforward movement of the said guide-bars, substantially as set forth. a
